A Researcher from the Centre National de la Recherche Scientifique (CNRS) Explores the Physiological Adaptations of Pregnant Orcas at Loro Parque
In a groundbreaking development for marine research, a team of scientists has successfully recorded the electrocardiogram of a pregnant orca in the final weeks of gestation. This study, conducted at Loro Parque in collaboration with the Centre National de la Recherche Scientifique (CNRS) in France, offers an unprecedented opportunity to analyse the physiological adaptations of these cetaceans during a critical period for species conservation.
The research, led by Angelo Torrente, a scientist at CNRS, aims to unravel the cardiovascular changes experienced by pregnant orcas. Using a non-invasive experimental system, researchers have obtained unprecedented data on the cardiac health of Morgan, a female orca in an advanced stage of pregnancy. The findings are expected to enhance our understanding of the metabolic and energetic challenges these animals face during this crucial phase of their life cycle.
A Unique Scientific Opportunity
The ability to study a pregnant orca in a controlled environment has provided an extraordinary opportunity for science. This study not only sheds light on the physiological demands of gestation in cetaceans but may also offer key insights into foetal development. In particular, researchers hope to determine whether the diving adaptations that allow orcas to voluntarily reduce their heart rate are also transmitted to the foetus while in the mother’s womb.
“This study is a clear example of how the care of cetaceans in specialised facilities enables scientific breakthroughs that would be impossible to achieve in the wild,” explains Javier Almunia. “Recording the electrocardiogram of a pregnant orca provides us with unprecedented insights into her metabolism and the additional nutritional requirements needed to successfully complete gestation—an essential factor in ensuring the survival of wild orca populations in situations where food resources are scarce.”
Advancing Animal Welfare and Conservation Science
Advancing Animal Welfare and Conservation ScienceThe collaboration between Loro Parque and CNRS underscores the value of applied science in animal welfare and conservation. The study demonstrates how research conducted in controlled environments can help answer key questions about the biology of endangered marine species while simultaneously contributing to their protection.
“The ability to study the heart of a pregnant orca represents a significant advancement in marine science,” states Angelo Torrente. “Such research not only enhances our understanding of these animals but also lays the groundwork for future applications in the conservation and management of wild populations.”
With this pioneering study, Loro Parque reaffirms its commitment to scientific research and the welfare of cetaceans, providing a valuable model for marine science and species conservation.
